Application
The odorizing injection system was
specifically designed to guarantee a
constant odorization rate regardless of
the gas flow rate, the type of odorizer
employed, and the required odorization
rate.
The odorizing systems used up until
now have several disadvantages from
the point of view of operation as well
as safety, as summarized below:
Very low precision.
Difficulties regarding calibration and
regulation.
Low operational flexibility
Difficulties in communications
between man and machine.
Our system solves all of these
problems and permits gas to be easily
and safely odorized.

Features
The control unit’s job is to control the
metering pump or injector according
to the amount of gas and odorizer
measured by its sensors, so as to
maintain a constant network odorization
rate that matches the set value. It is also
able to record in an internal database
the alarms and logged data that can be
read by the appropriate software.
The equipment can be queried in the
field or by a remote system.
A display with keyboard that makes
it possible to view and modify all the
quantities is available for use in the
field.
The remote system is comprised of
a Windows PC on which is installed
the communications software that

can dialogue with the peripheral via
direct serial connection (RS232) or
via analogue modem or GSM.
An (optional) printer is available. If it is
connected to the control unit via the
RS232 serial port, it will generate a
printout of the hourly data recorded at
the end of the day and at the end of the
month.
The amount of the gas to be odorized
can be received from fiscal calibrators
with a 4-20 analog signal or impulse
signal, or directly from sensors in
the field such as meters or DELTA p
transmitters.
The control unit is able to control the
automatic actions of the emergency
systems, such as the lapping odorizing
system or other systems.

Configurazione
Configuration

The lack of precision inherent to the
lapping system is compensated for
by the system’s operating principle.
The electronic regulator receives
the amount of gas dispensed and
the amount of odorizer injected
and, based on its programming
parameters, it sets the number of
impulses to be sent to the injector
or the metering pump to guarantee
the set odorization rate.

The system is easily calibrated and
regulated. The startup operations
are simple and intuitive and are
completely guided by interactive
software menus. You just need to
program the system’s typical data,
the type of odorizer liquid, and the
required odorization rate.
System safety. The size of all the
components was established to
be able to withstand the system’s
maximum operating pressure.

This system consists of one or two
metering pumps, a flow switch,
and a series of mechanical and
electromechanical components
connected together by means of
stainless steel pipes equipped with
A-LOK connectors.
These components are controlled by
an electronic control unit and perform
the following functions: signaling,
interception, containment, and
injection into the network.
The odorizer is drawn from anchored
tanks, in the form of lapping odorizing
system or portable drums.
The liquid is sent to the metering pump
which pushes the odorizer toward the
injector, causing it to pass through the
flow switch.
The control unit receives a signal from
the flow switch each time the pump
injects odorizer.
The metering precision is signaled to
the pump, which is equipped with a
manual adjustment mechanism to
set the amount of odorizer injected at
each stroke of the pump.

This system consists of one or
two metering pumps, a capacitive
probe, and a series of mechanical
and electromechanical components
connected together by means of
stainless steel pipes equipped with
A-LOK connectors.
These components are controlled by
an electronic control unit and perform
the following functions: signaling,
interception, containment, and
injection into the network.
This model must be installed together
with anchored tanks, in the form of
lapping odorizing system.
The system functions in cycles and
utilizes a series of communicating
vessels. Each cycle consists of a
loading phase and an emptying phase
of the capacitive probe.
The pump draws the odorizer from the
capacitive probe during the emptying
phase.
The solenoid valve located at the
odorizer entrance isolates the tank
probe; therefore, the liquid inside it
decreases after each stroke of the
pump.
The control unit reads the amount
of odorizer injected by checking the
difference in the level inside the probe.
It then compares this amount with
the gas flow rate and varies the pump
speed to guarantee the set odorization
rate.
Because this system is installed
together with anchored tanks and is
equipped with a capacitive probe, it is
able to indicate the actual level of the
tank as well.

This system consists of one or
two metering pumps, a mass flow
meter, and a series of mechanical
and electromechanical components
connected together by means of
stainless steel pipes equipped with
A-LOK connectors.
These components are controlled by
an electronic control unit and perform
the following functions: signaling,
interception, containment, and
injection into the network.
The odorizer is drawn from anchored
tanks, in the form of lapping odorizing
system or portable drums.
The liquid is sent to the metering pump
which pushes the odorizer toward the
injector, causing it to pass through the
mass flow meter.
The control unit reads the amount
of odorizer from the mass flow
meter which quantifies with extreme
precision the mass of the liquid passing
through. It then compares this amount
with the gas flow rate and varies the
pump speed to guarantee the set
odorization rate.

Odotronic - S
This system consists of one or more
metering pumps, a reserve tank
(7 or 24 liters) with a level switch,
a flow switch or a flow meter, and
a series of mechanical, electrical,
and electromechanical components
connected together by means of
stainless steel pipes equipped with
compression connectors.
These components are controlled by
an electronic control unit and perform
the following functions: signaling,
interception, containment, and
injection into the network.
The odorizer is drawn from a tank or
portable drums.
The liquid is sent to the metering pump
which pushes the odorizer toward the
injector, causing it to pass through
the flow switch which quantifies the
injected odorizer.
The control unit receives a signal from
the flow switch each time the pump
injects odorizer, and quantifies the
volume that is injected.

This system consists of a solenoid
valve injector, a capacitive probe, and
a series of mechanical, electrical,
and electromechanical components
connected together by means of
stainless steel pipes equipped with
A-LOK connectors.
These components are controlled by
an electronic control unit and perform
the following functions: signaling,
interception, containment, and
injection into the network.
This “pumpless” Odotronic model must
be installed together with anchored
tanks, in the form of lapping odorizing
system.
The system functions in cycles and
utilizes a series of communicating
vessels. Each cycle consists of a
loading phase and an emptying
phase of a meter of a known volume,
consisting of a capacitive probe.
The pump draws the odorizer from the
capacitive probe during the emptying
phase, due to the pressure generated
by the pressurization unit of 0.5 bars
greater than the network pressure.
The solenoid valve located at the
odorizer entrance isolates the tank
probe; therefore, the liquid inside it
decreases after each injection.
The control unit reads the amount of
odorizer injected by instantly checking
the difference in the level inside the
probe. It then compares this amount
with the gas flow rate and varies the
speed of the solenoid valve injector to
guarantee the set odorization rate.
Because this system is installed
together with anchored tanks and is
equipped with a capacitive probe, it is
able to indicate the actual level of the
tank as well.

Customized Odotronic
These systems are designed to be
used in refineries, loading bays, and
wellheads to add odorizers, denaturing
substances, or additives to LPG gas.
These systems primarily consist of
metering pumps, a metrologically
certified mass flow meter for the
injected additive, and metering control
unit to prevent loss of odorization.
The liquid can be drawn from portable
containers or anchored tanks which
allow the amount of residual liquid to
be measured by means of a scale or an
electronic level gauge.
The control unit receives the signal
controlling the in-line meters and
scales and injects the amount of
additive according to the setting.
The system can be enclosed in a
stainless steel cabinet.
